Chemistry Scientists replaced 40 percent of cement with rice husk cinder, limestone crushing waste, and silica sand, giving concrete a rubber-like quality, six to nine times more crack-resistant than regular concrete. It self-seals, replaces cement with plentiful waste products, and should be cheaper to use.

In Southern Canada we get tempretures that swing between -40c in the winter and +40c in the summer. Concrete on structures is constantly being touched up and any roads made of it are often in pretty rough shape. Most of them are asphalt.

How can people live in places where the weather cracks the buildings you live and work in? I live in England and it's cold enough here in the winter (especially in this house). Canada sounds terrifying

I had to work outside all day in -55C a few years ago. Luckily it warmed up to -40 for the rest of the week. I think I would actually die if I went anywhere really warm like Florida.
